<font face="Arial">I've been handed a PS3100 to work on --<br>
when powered up, it makes a sound as if all keys are being
pressed; after about ten seconds, this dies away.<br>
The only output after that is a very faint sound from the Direct
jack when keys are pressed.<br>
Power supply is good, and control outputs from the patch panel
(envelope, MG, etc) are correct.<br>
<br>
My two problems with working on this synth are<br>
1) absolute lack of meaningful documentation, aside from a few
hand-drawn schematics<br>
2) that damned card cage, getting in the way of everything.<br>
<br>
My question is: has anyone here successfully worked on one of
these? Any advice, or pointers towards some useful documentation?<br>
<br>
Thanks.<br>
